I don’t think there is any documentation on this. If there is, David Intersimone at Embarcadero is who I’d ask for it. Failing that, there are two options you might try. Create some “bare” unit tests with what you want and save them as templates Write your own wizard in Delphi to create unit tests … Read more

Here’s a quick console demo of declaring custom attributes for: Enums Function type Procedure type Method type (of object) Aliased type Record type Class type Record type that’s internal to a class Record field Record method Class instance field … Read more

The extra effort you’re seeing is almost certainly due to antialiasing. When the line thickness is less than one pixel and the line doesn’t sit squarely at the center of a row … Read more
Everybody is just writing about negative issues so let’s stress some positive issues. Errr, the only positive issue – less (in some cases much less) typing. I wrote GpFluentXMLBuilder just because I hate typing tons of code while creating XML documents. Nothing more and nothing less. The good point with fluent interfaces is that you … Read more

Otherwise, when running in a WOW32, the OS assumes that the app is expecting the same environment that it would have on a 32-bit OS which means that of the 4GB of … Read more
Of course you can use IfThen(SomeBooleanExpression, IfTrueReturnValue, IfFalseReturnValue) where the return values are numeric (uses Math) or string (uses StrUtils). But notice that this will evaluate both arguments in all cases — there is no lazy evaluation, so it is not as efficient as the ?: operator in C#, where only the right operand is … Read more
You have a big challenge ahead of you. I had a similar challenge ahead of me — 15 year old monolithic single threaded code base, not taking advantage of multicore, etc. We expended a great deal of effort in trying to find a design and solution that was workable and would work. Bad news first. … Read more
why did not delphi give any error saying the length is beyond 255 for myExtremlyLongString? You have your answer a bit down in the text in section Long String (AnsiString).
